I was on a server with less than 16 players having a conversation. Later more than 16 players came in, cutting the conversation short. When we tried to use !votealltalk, it turned out that it was an admin command. I was wondering if you guys could make it useable by anybody again.

We've had this asked a few times. We have no real plans to allow Votealltalk, because simply if we did, the servers would never not have all talk on. It gets very spammy with 20+ people on, and people would never vote it off, even when it should be.
